Specicaton of Letters Patent.

Patented April 20, 1909.

Application led November 30, 1908. Serial No. 465,317.

To all whom 'it may concern:

Be it known that I, HARRY A. EVERY, citizen of the United States,residing at Boston,

chusetts, have invented a certain new and useful Improvement inInsulated Tools for Marking with Metallic Leaf, of which the followingis a specification, reference being had therein to the accompanyingdrawings.

In marking with metallic leaf such for instance as gold leaf, uponvarious objects, itis common to lay the metallic leaf u von the objectto be marked, the metallic eaf having superimposed upon it a suitablebacking of paper or other sheet material, and then to im ress u on thebacking, either by a heated rol er or by a pointed instrument or othersuitable tool which has been heated, the outline of the design that itisintended to transfer in metal to the object to be marked.

In order to cause the gold or other metallic leaf to adhere to theobject to be marked along the line traced'by the marking instrument, itis necessary that the marking instrument should be heated, When thismarking instrument is a hand tool, such for instance as a metallicpencil or stylus, it is necessary to have an insulated or non-heatconducting hand grip in order to avoid burning the hand, and also toserve to prevent too rapid radiation of the heat from the point of thetool. v

The object of my invention is to provide a marking tool for marking withmetallic leaf having an insulated Enger grip for the purposes above setforth.

T from the following description taken in connection with theaccompanying drawings, and the novel features are pointed out andclearly defined in the claim at the close of the speciiication.

In the drawings :Figure l is a plan of a tool embodying my invention.Fig, 2 is a longitudinal section. Fig. 3 is a plan of the insulatingsleeve detached; Fig. 4 is a plan of the point and Fig. 5is a plan ofthe handle rod detached. Y

Referring to the drawings,-l represents the point of the toolwhich ismade somewhat e invention will now be fully understood conical and is ofmetal, 1preferably steel, and is formed with a shan 2 extendingrearwardly, the said shank being of considerably in the county ofSuolkand State of Massaless diameter than the diameter of the rear endof the point l, thus forming a shoulder 3 at the junction of the shankwith the rear end of the point. The shank 2 is` tapped out forming ascrew-threaded socket 4. A metallic rod 5 ofthe same diameter as theshank 2 is formed with a reduced forward end having a screw-thread 6which is adapted to screw into the tapped out socket 4. The rear end ofthe rod 5 is provided with a head 7 which may be either integraltherewith as shown, or it may be a nut adapted to screw onto the rearend of the rod.

An insulating sleeve 8 of any suitable nonheat conducting material, butpreferably asbestos or asbestos composition, is provided which isadapted to fit over the rod 5, the rear end of the sleeve abuttingagainst the head 7 and the forward end of the sleeve abutting againstthe shoulder 3 when assembled. In order to assemble the parts, the rodis first inserted into the sleeve until the rear end of the sleeve abutsagainst the head l7 and then the shank 2 of the point is inserted'intothe opposite end of the sleeve from the head 7 andscrewed onto thethreaded end of the rod, bringing the shouldered end of the point backup against the forward end of the sleeve, thus clam ing the sleevebetween the shouldered end of) the point and the head 7. Theinsulating'sleeve thus forms the hand and finger grip which entirelyprotects the hand and fingers from the heat even when the point ishighly heated for use and also materially aids in preventing too ra idradiation of the heat from the rod and t ereby retards the cooling ofthe-point. The parts are easily assembled and detached.

at I claim is:

An insulated tool for marking comprising a metallic point member havinga rearwardly l projecting shanliportion of reduced diameter forming ashoul er at its junction with the head, said shank having a ta ped outsocket in its rearend, a metallic rodlhaving its main portion of thesame diameter as said shank,

one end being reduced end adapted to screw 1 the sleeve between the seidshouldered end into said socket and having its other end proend the headof the rod. l0 vided with a head, and a sleeve of insulating n testimonywhereof I affix my signature, materiel which is adapted to iit over saidin presence o1 two witnesses.
